Abstract
The paper presents results of a numerical analysis focused on an identification of mechanical properties of an element created by using Fused Deposition Modelling additive manufacturing technique (FDM). There is presented a description of technology of the 3D printing, numerical model created by using the finite element method (FEM), as well as some problems referred to estimation of the mechanical properties of the printout. The main point of the research was a study of relationship between properties of the rectangular infill structure (described in the micro scale) and the global values of selected mechanical properties of the part (described in macro scale). The numerical models of infill were created by applying the ABAQUS 6.12-1 software. The scope of the study involved tests performed in linear elastic limit of the material behaviour by applying uniaxial compressive load and two types of boundary conditions. Also, three alternative methods for identification of mechanical properties of the infill structures were presented. The results of the study of relationship between the density of infill structure and the Young's modulus of the printout were presented and discussed.
